Definition

Namespace:

Event Type

WritingCompletedEventHandler

Examples

The following example shows how to use the WritingCompleted event.

C#

private void SaveMultipleFixedContentDocumentsAsync(
             XpsDocumentWriter xpsdw, FixedDocumentSequence fds)
{
    _xpsdwActive = xpsdw;

    xpsdw.WritingCompleted +=
        new WritingCompletedEventHandler(AsyncSaveCompleted);

    xpsdw.WritingProgressChanged +=
        new WritingProgressChangedEventHandler(AsyncSavingProgress);

    // Write the FixedDocumentSequence as a
    // collection of documents asynchronously.
    xpsdw.WriteAsync(fds);
}

// Cancel an async operation
public void CancelAsync()
{
    _xpsdwActive.CancelAsync();
}
